Create Sigmafine Balance Analysis Cases

The analysis rule may require an Initialization Case to exist if inventory (tank) elements are in the model. If no inventory elements are in a case, you can run the analysis completely in the initialization case. If the measurement value for the opening inventory has been selected to use the value from the previous case, then you must initialize the analysis series as shown in this section.

Before creating cases, check the section on Time Rule and configure a time rule for this Model Analysis.

To configure the analysis rule, follow the steps below using either the System Explorer or the Modeler.

  1. Follow the steps under either System Explorer or Modeler.

    ClosedSystem Explorer

  2. In the Model Analyses navigation pane, select the Model analysis for which you are creating a case.Figure 238: Sigmafine Analysis Model - select New case

  3. Click the Case menu button and select New.

    ClosedModeler

  • On the SF Analysis Toolbar, click the New Case button.Figure 239: Modeler - SF Analysis Toolbar - New Case button

  1. Use either System Explorer or Modeler to change the times for the Case to match a Case for the source analysis (Mass or Volume Analysis). For detailed instructions, \see the topic under Server & Client.

    This manual change of times is necessary to start the Case series.

  2. Use the Case Runner to run the Collect Elements, Collect Transfers and Collect Inputs steps, as shown in the following image.Figure 242: Case Runner - Collect Elements, Collect Transfers and Collect Inputs

  3. If the analysis contains no inventory elements that are set to use the value from the previous Case as the opening inventory, you can continue running the Case through completion (using the Run and Publish steps). Otherwise, the first full Case that will be run and then published will be the next case.

  4. Check-in the Case or continue on to create subsequent cases.

    After the first case, Sigmafine uses the established Time Rule to automatically assign start and end times to the subsequent cases.

    To create more cases, follow the same procedure as described above to create the first case. If you examine the Case properties of this new case, note the previous Case as the initial Case described earlier.

  5. Use Case Runner to run all analysis steps (or choose to run each step separately) and view the log and results tabs to see the results from each step of the analysis.

  6. Click the buttons in the Case Runner to execute the analysis.

  • If Case Runner is not visible, on the View menu, click Case Runner.
  • If the checkboxes are not visible, right-click on Case Runner and select Configure to customize the buttons.
  1. To view the log and results tabs to see the results from each step of the analysis:
  2. On the Log tab, view any errors or messages from the Analysis and if enabled, from the Gross Error Analysis checks.
  3. On the Results tab, examine the results of the Analysis.
